Moving tags in JOSM

[Bjoern Hassler]

Dear all,

I've got a couple of questions about moving tags  in JOSM.

(1) The only time you get a "merge tags" dialog seems to be when merging
nodes. E.g. copy/paste tags overwrites silently and utils2 functions also
overwrites silently. (Though e.g. you could use Shift+R to go from object 1
to object 2 and then back to object 1 to preserve object 1 tags.) Is there
an option/plugin that can marge tags from a node into a way, with a merge
dialogue (or a "do not overwrite existing tags" option)?

(2) Is there a way of copying/moving tags from a node or way to a relation?
Ideally something like "move tags to relation" -> "select tags to move" ->
"select relation to move to (if more than one)" -> move. I am sometimes
moving wikidata/wikipedia tags from nodes/ways to relations, and there
doesn't seem to be a simpler way than manually copying them one by one.

Many thanks!
