"Tab Also Current for Pages" is automatically cleared when reusing page

Question

I'd want to reuse a page, and include it in the "Tab Also Current for Pages" list of 2 standard tabs, that are displayed conditionally. But when I include it in the second tab, it is automatically cleared in the first. This only happens in the detail Tab edit screen, in the multi tab edit screen the pagenrs are not cleared. So I can achieve what I want, but for future maintanance this is very risky.
Is there any way to avoid this?

Hi Capt Egg
I didn't mean to say that there wasn't a case for a page being associated to more than one tab -- quite the opposite! More than once I wished that could be done...
But the fact is that currently in Apex we have:
- A tabular form that allows you associate the same page to multiple tabs (and worth mentioning, allows you to enter anything in the Also Current Pages column, not only a list of page numbers!)
- A form that doesn't allow you to do so, and validates if you entered a list of valid numbers in the Tab Also Current For Pages field.
Something needs fixing, and in my experience with Apex the forms I've seen seem to be much more strict in terms of validations than tabular forms for a number of reasons.
I am guessing that the form is the correct one and implements the intended rules. If that is true, the potential bug in the tabular form may be fixed in the future and the OP won't be able to maintain his applications that used this hack anymore.
Or maybe not, maybe the bug is in the form. But I would seek clarification on this before going down this route...
