Flow set fron other node

General
1

Hello
I have written a node to which many functions communicate via a flow set /flow get.

Now I want to reset this value from a completely different flow by setting int to 0. But it is not a global variable and I don't want to edit a lot of functions to rewrite everything to global.
Is there a possibility to influence the flow in another node?

You can use a link call node in the other flow tabs, this link call can call a link in and out nodes in the function flow tab to update the flow var. Or possibly just link out and link in nodes, depending if you require a returned message or not.
