Adding my additional requirement (non-permanent solution) would sort of change the question itself.
Yes, yes it would. In fact, that would make your question a different question, which should be asked separately.
It is, however, a related question, so your new question should also link to the existing question, along with a clear statement that the existing question is similar, but not the same. (I have seen people simply stating that an existing question is not the same. You should do more than that: make the differences very clear.)
Linking serves three purposes:
- The link demonstrates that you have done your research.
- The clear explanation of differences makes it less likely that another user will try to close your new question as a duplicate of the old one.
- Some of the answers will overlap, so having a link helps the answerers. They can look at what research has already been done, and build on it.
That third bullet point may not be true in the case of this specific question, but it certainly is in general.
