Add ways and perform 'Zoom to Gap' in one go

[Polyglot]

I'm creating/correcting and updating thousands of route relations for all variations of public transport. One thing I find I'm doing over and over again, is select some ways, add them to the relation, (sometimes sort the selection, in case the ways were selected out of order), then 'Zoom to Gap' of the next continous stretch.

It would be exremely handy if those 3 actions could be performed by clicking a single button of the relation editor.
