Delete some data from a segment

Hi,

I had 2 segments based on page url contains.
Segment 1: page url contains dm-home
Segment 2: page url contains edm-home

Recently, i realized that all data in segment 2 is also in segment 1. Then i changed the 2 segments to this:
Segment 1: page url contains /dm-home/
Segment 2: page url contains /edm-home/

Now, i want to delete all the old data that match edm-home from the segment 1 archive. Is this possible ? If yes, how do i do this ?

Thank you in advance for your reply.
