Auto-numbering sequence from last number used

Question

Is there a way to set the Filename Template Editor and the Text Template Editor to automatically start numbering a batch of images from the latest number used?
At present in Editor, one has to set the Start Number manually. I am using this feature on photos that were imported into LR long ago and am now getting around to editing, processing, cataloguing them. Part of that process for me is renaming them, giving each a custom+sequence Filename, for example "DDOH-3256".
The way the text editor is set up now, I have to remember what I was working on most recently, find it, check what the last sequence number was in that batch, then set the next available sequence number in the Text Template Editor.
I used to use IView Media Pro and it had a lot more naming and re-naming conventions, including. It would be great if LR had the same options.
Thanks for any help or feedback,

Hi,
I have a sequence and i am using that in a procedure to insert records.Often the procedure throws error like primary key violated.
When i checked the last number used by the sequence it gave me as 27331 and the currval of the sequence as 27312.
Please advice us to rectify this.First make sure that you understand the difference between a primary key and a sequence.
A sequence is just a number generator. Oracle guarantees that the sequence will give you a new unique number each time that you call NEXTVAL. If the sequence is cycling then it can even generate the same number again after some time but this is rarely the case.
A primary key is a constaint on your table that requires all values in the column to be unique and not null.
When you get an primary key violated error then you just tried to insert a value that was already there in the table.
Some scenarios might be the reason for this.
<li>You insert a row using the sequence. You insert a new row using the same number again without fetching it from NEXTVAL (e.g. using currval instead of nextval, or not updating a variable that holds the new ID,...)</li>
<li>Somebody else already inserted an ID without using the sequence</li>
<li>A variation is when you import data from another database and resetted the sequences</li>
<li>There is some test data in your tables. The test data was inserted in a high ID range to separate it from the real data. Your sequence just reached this range.</li>
