Request fulfilled Filtering by Platform(s)?

I apologize if this has already been answered elsewhere and I'm just wasting your time, but is there a way to filter the trades section by the platform we use? I've been trying to find some items for sale, and almost every time I click on a trade it's for a PC user. So far I have only been able to make one single trade because I cannot see others' platforms until I click on the trade and it shows the Windows/PlayStation icon next to their profile. Again, sorry if I'm just wasting time and space here on the forum. I am also on mobile if that attributes to my problem.
