Can a rule return a subset of bucketset

Question

Hello,
I am trying to implement a rule, which schould return a list of values. The example is thourght up, so you do not need to question the relevans. The real case is for a financial institute, so I cannot reveal the true details.
Imagine that a student signs up for 2 courses on a university. The courses does not use the same materials on the different universities, and in some cases the student might aquire books which will be able to cover both courses, which will make it cheaper for the student. (eg. if a student chooses math and chemestry on one university, the student might just buy the book "math and chemestry", antother university might not allow this, because they cover a subject which is not in "math and chemestry" and the student then has to aquire the two books "math" and "advanced chemestry")
The rule schould use a decision table, and return a list of strings with the ISBN numbers of the books the student schould aquire.
There are 3 bucketsets, universities, courses and approvedBooks
There is an xsd which defines rule request and response, which has been used in the rule designer to create the corresponding Facts.
When I make this setup, I can use the bucketset to control the values of my request fact, but i cannot assign a bucketset to the response fact, because it is reconized as a list.
<xs:complexType name="booksToAquireResponseType">
<xs:sequence>
<xs:element name="bookName" type="xs:string" minOccurs="1" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
If i implement it so that only one book i returned:
<xs:complexType name="booksToAquireResponseType">
<xs:sequence>
<xs:element name="bookName" type="xs:string" minOccurs="1" maxOccurs="1"/>
</xs:sequence>
</xs:complexType>
Then I can assign a bucketset to the response fact, and then the book to aquire can be selected from the drop down in the action section of the rule designer.
My problem is that it is nessasary for me to return a list of values, does anybody know how to solve this, or does anybody know if it is an error in the rule designer, that a list cannot be assigned a bucketlist? (The request fact is recognized as a list of strings, so I would expect that I could assing a string-bucketset to the fact, but the bucketset-dropdown i empty)
I know of two solutions which wont be satisfying.
+1: Hardcode the response list. Hardcoded values cannot be handled in the web composer, so the business people wont be able to administer their own data, and change the response.+
+2: Create a bucketset for each possible book combination, and create a function, which will return an entire bucketset. This will give alot of redundant data, and if one book comes in a new edition, alot of bucketset values has to be updated, istead of just one value, wich all results reuse.+

Hi,
1. Based on my knowledge, "an email sent to my inbox is automatically sent to an Outlook folder", we can't create a transport rule to achieve it. But we can create a Inbox rule on Outlook or OWA to achieve it. Here is an example：
2. About point 2, you can create a transport rule on EAC or EMS to copy the message user1 received to a mail contact(external email address). Here is an example for your reference.
Hope it helps.
