Redirect nvim call inside fterm to outter nvim

[ds82]

Is it possible to route a call to nvim inside a fterm window to the outer nvim instance?
E.g. I use tig inside fterm. If I commit something inside tig, tig opens nvim for the commit message, but this is another nvim instance inside fterm. Is it possible that the outter nvim (the one that opened the fterm window) open the git commit message editor?
