You can filter the content in the stream activity gadget by putting the space ID in the macro syntax as we can see in the documentation
None specified (i.e. display content in all spaces)
Filters the content by space. This gadget will display only the pages etc. which belong to the space(s) you specify here.
If you set the space there it should bring just the content of that space.
I hope this helps,
In addition to my answer above, if you'd like to filter by specific pages, I believe this is not possible at the moment, so I've created a feature request for you here: https://jira.atlassian.com/browse/CONF-33806
I recommend to vote and ask your colleagues to vote as well to increase popularity and the chance to be implemented in the future.
