Imbued gems not useable with MTX's

To whom it may concern,

I've imbued my Lightning Arrow gem with a lvl 1 Mirage Archer support and you do not have the option to put an MTX onto the imbued Mirage Archer. I don't like the green guy I want to use my Blue guy. I'm unsure if this is the case for other gems that have been imbued as well or it's contained to Lightning Arrow w/ lvl 1 mirage archer only, but I'd like to use my MTX on imbued items. It should allow for both a Lightning Arrow MTX AND the imbued aspect to have an MTX at least if you guys enjoy moneys. I searched up other things with imbue, and gems and I didn't see anything else related to this if there was I apologize and please lock/close topic. Have a nice day.
