Is there a way to add a tag to all ways that were last edited by me in a given area?

I have added and corrected many many buildings, coastlines, rivers etc. in the North East Greenland National park. This tiny area Relation: ‪Kalaallit Nunaanni nuna eqqissisimatitaq‬ (‪8515283‬) | OpenStreetMap

Most have been created with JOSM and credited to my main data sources (the ones that stated the mere existence). However Maxar Premium was used to put everything right as to shape.

Thus they should all have “source:geometry=Maxar” added to them.

If I make a turbo overpass query to get all out is there then a way (that even I could understand) to add this tag to all?
