tf2 multiple maps over 64mb net_maxfilesize limit

I want to use 2 custom maps on my server that are over the 64mb limit so i compressed them and uploaded them to drop box. I got the download link from dropbox and put it in the downloadurl inside server.cfg and it worked. the only problem is i can only do that for one of the maps!

How do i do it with 2?

Thanks for any help!
