this would be super useful in DF where a party member's gear breaks then you lack the dps to clear a fight. Which has happened to me multiple times in he vault and If there was a way for me to fix their gear we could have solved the issue right there instead of asking him to leave so we could clear it
it could be like a little mini menu showing the repair cost that would be paid to the crafter doing the repairs, use the crafters dark matter then click accept and let the repairs happen
