21449	Replace relations/multipolygons	nkamapper	team	"It would be very efficient to have support for replacing one relation with a new one. The typical use case is when importing data which contains many multipolygons, for example buildings or nature reserves, which needs to be conflated with existing multipolygons in OSM. In this situation, I would like the existing multipolygon to be updated not only with members of the import relation, but also with the tags of the relation. And then for the import relation to be deleted.

There is already support for updating members of relations with the ""Update multipolygon"" function, but not for the tags of the relations. The ""Past tags for previous selection"" function could have been used, but it is very difficult to get the order right between the two relations.

The new functionality could be added as an extension of the ""Update multipolygon"" function or as an extension of the ""Replace geometry"" function.

I sometimes have hundres of multipolygons to replace, so this would certainly be a helpful enhancement."	enhancement	new	normal		Plugin utilsplugin2
