Changing Layout when opening a record

I am looking for a way to select a layout based on a date calculation
when openning a record.

Here's the details - I have a database of stocks that I have sold. When
I open a record, I want it to open with layout A if the date of the last
sale of this stock was 31 days or less and another layout if the the
last sale was over 31 days ago.

Can this be done with FM 7? I am thinking of updating to FM 8.
