Can we preview Fists of Stone mods in game?

This is more of pre-emptive feedback because I've been unable to find any communication from GGG along these lines.

Are we going to have any way to preview what a pair of fists of stone gloves would be in game? I couldn't find any mention of this in the reveal, teasers, or Q&A. Has this been addressed somewhere already?

If we don't have a way to preview them in game, it will be very difficult to buy or craft a pair of gloves to be used as fists of stone until tools like poedb and path of building have figured out which mods are transformed and to what. Even once that happens, it will require use of external tools, which feels like a step in the wrong direction for the patch that's adding build files and in-game price checking to keep players inside the game.

I'd love to be missing something like a post where GGG has already commented on this. If I'm not, please add a way to preview fists of stone prior to equipping them in the game directly.
