Mass-editing tags doesn't delete the current tags (add tags instead of replace)

[enoversum]

I'm using solidtime mostly via projects and tags to categorise time entries (e.g. 'design', 'communication', 'technical stuff', 'programming'). What I'm exactly working on is left in the description, so I circumvent tasks at the moment. To handle and filter time entries, since there is no status field, I also have a 'billed' and 'paid' tag that I want to apply to entries that have been billed or paid already. However, when mass-editing tags for time entries, all other tags get removed. I'd love an option to add rather than replace current tags with one or more new ones.
