I wanted to create short links only on a specified urls shorteners - I posted on all, and selected like 170 of them. I faced here a few issues:
1. I see that gsa created more shorteners than in the engine selections menu (it's really good) but how can I be able to pick the proper ones- I guess in the engine selection we see groups of shorteners - is here a source for that?
2. Because the above way was not possible I tried to import those selected urls to a new project - but despite I imported them, gsa was again posting on all url shorteners.
