Pull request - Custom Merge Checks

[tdacox]

I would like to implement a custom merge check for my company. Based on some criteria, we would like to popup a warning message and capture some text and then use that text in the merge commit message.

For example, we may use this to prevent WIP commits from being merged without a justification being entered by the merger. Another thing we may check is the base of the branch being merged in: the warning would indicate that a rebase is recommended (but not required) if the base of the branch is X commits behind.

I have the SDK installed and am looking at some samples. None of these help me to understand if having a popup and capturing some information is even possible.

Can anyone provide some guidance here? 

Thanks in advance
