I would like to "hook" into process of getting name and description of concepts from my Language. Previously I've done some investigations and found a workaround for my task with Transformation/Substitution menus (https://youtrack.jetbrains.com/issue/MPS-31999) but this workaround requires a lot of handlers and unnecessary editor changes. So I don't like this solution.
My idea: create some hooks for the process of getting names and descriptions. But I don't know is it real or not. For example, I saw "ConceptDeclaration" but conceptDeclaration change language source.
I would like to change dynamically "Arm" and "[Arm definition]" in a flexible way. For example, when MPS will derive concept name I would like to change default "Arm" to something else.
