[CON-204] Refactor with Continue

[sestinj]

Is your feature request related to a problem? Please describe. When I change a type, it's a very repetitive process to update all usages.

Describe the solution you'd like An easy way to specify a) the symbol for the type that is being changed, and b) a description of the change to be made, which is probably just a matter of showing the old and new types and asking for update

This should be built as a step + slash command first, but then might turn into eventually some better UI to go along with it
