Move programs and games to external storage

I want to move some programs, games from MacBook Pro SSD to the external HDD. With Xcode it was no problem. Because Xcode was under Applications and I could copy it and create link to it. But I have some games that are not asking about installation path. And that are installed in many different places on my SSD. For example under User->Documents etc. If I move it simply to an external drive - it doesn't work. I think they have some internal references, maybe under config files, to each part. I want to move - GarageBand (with all additional sounds etc.), WarThunder and World of Warships from internal to external drive. Are there any general solutions to move the programs and games
**that are not stored under Application?** Or maybe guides, articles etc.
