Custom SF Symbols for Box Drawing?

I'm trying to find out of SF Symbols is the correct tool for job I have in mind.

I'm wanting to create custom box drawing symbols, like those in the unicode block.

Box drawing requires the lines from one symbol to connect to the lines of an adjacent symbol. Does SF Symbols allow for this connecting of symbols, or does it create some padding restriction around each symbol, preventing lines from connecting to one another?
