Flashbacks & Legends TA2 Collections

I see they include Topps Now and 42 series cards. If I locked these in F & L collections, would that lock me out of the 42 series for 99 Jackie? Or the voucher for Topps Now for Mo? I'm 2 cards short for the TN voucher.

Once collected you can use them in as many collections as you want

cards can be used in multiple collections

Thanks guys

Just don’t be a DumbA like me, and accidentally put them into an TA exchange set before collecting them.
