Is it possible to merge across multiple gitgraphs

Is your feature request related to a problem? Please describe. In real life, we might have multiple master branches (which are not branched out from a single source) on the same level and merge into each other.

Describe the solution you'd like I would like a solution that enable users to create multiple gitgraphs on the fly and merge into each other.

Describe alternatives you've considered if multiple instances of gitgragh is able to recognize each other and treat each other as a branch. That would be alright as well
