Easy way to add a single translation unit to a TM

There seems to be no easy way to easily add a single translation unit to a TM; plenty of forums exist where users have vented their frustration at this and have needed to suggest workarounds which really shouldn't be necessary (a T-Window plug-in or to even overwrite an existing unit in the TM, such as a duplicate). Is there a reason this basic database function has never existed in Studio (as it does in Madcap Lingo)?
