Thank you for your post.
I would encourage you to enter this into our Feature Request web form at:
Although I can copy your post and paste it into the web form, there are some personal questions asked that only you can answer.
For now, there is another workaround by having Commit Records prior to the Go To Related Record script step. That way, you don't have to rely on the user clicking outside the portal to save the changes (workaround #1), and you don't have to copy the row record ID and finding (workaround #2).
