Merging terms manually in MultiTerm 2019

While I work in MT, it's sometimes hard to tell impromptu if a term is eligible to be merged with another one. Oftentimes, there will be a suggestion for a term to be merged even if it's entered under a different category or subject. I am a beginner and being careful, I've left quite a few terms out without merging in my termbase. Hence the following questions:

1) Is there an option to manually merge two hand-picked terms as a form of termbase management after the primary editing is done and after choosing the 'Duplicate' command?

2) Or is there a batch option that would allow me to see the terms next to each other before deciding if they should be merged? We are talking same termbase here.

Thanks,

Marta
