[SuperJMN]

It not possible to specify a SharedSizeGroup name :(

Since there is no access to row definitions or col definitions its not possible. Do you have a suggestion for how to add this? Do you want to submit a pull request?

I'm running into the same limitation. Any chance this pull request will get merged and the change end up in the NuGet package?
