context menu - exchange same greens with blue

[tester]

There would be nice/handy option if I could using the context menu on specific primitives - change the green/signal primitives into the same but blue/signal type. For example change between green and blue "multiply" or "div" primitive and so on. Sometimes I do things in green, and later when I change my mind to an idea - I need to connect blue node there. Because can't do this - I need to exchange all primitives manually (or I'm missing somethiing?), also manually rebuilding all connections. It takes time, but sometimes produces errors on human factor side Input/output nodes can be edited that way.
