A button will be helpful that will run all the solutions of a problem sequentially. After making some changes to a problem, all the submissions are required to be re-evaluated one by one. A button that will re-run all the solutions will help a lot. But it’s not mandatory.
This issue has been a work in progress for quite a while. I wanted to build it on top of a few other behind-the-scenes improvements to Drafts. And, they are mostly done.
Hopefully we will have this feature soon in sha Allah.
