Excel macro find range under a specific text and then copy

Hello,
I have the following macro written by one of your colleagues. It finds the latest workbook (by date) in a datafile and copies a specific range from a specific worksheet to a range in a separate workbook.
It all works fine. Now I would like an addition.
Rather than having a set range (in the case below, Range("A1:R80")), the macro should search column B until it finds the following text, “OTC FX Options Position Breakdown”, and then it should select the range immediately below, Bx:Jx+10 and copy as before.

So, if the text appears at cell B20, the range would be B21:J31

The range in the second worksheet will remain constant.

Thanks,
CC
