When editing a long relation (an hiking trail), this is impossible to select the relation in the list, neither pas it's name or id.

2. select the next way
3. under relation(s) press + button to add a new parent relation

4. type de name or select the hiking route in the dropdown list

5. that' work fine 😎

Repeat this, but select few or more ways.
The map was scrolled and the last member of the relation isn't visible : you can't select the relation in the list.

1. select the next way
2. press MAJ and click on the next way along the route
3. do this again
4. press + and try to type the name of the relation : the list is empty 😞

Pasting the relation id would useful 😃

4. type de name or select the hiking route in the dropdown list

This usually works if you prefix the relation ID with r. (This used to be a requirement in the search bar too, but it was later relaxed to allow a bare number.)
