You can also use the repost tool and make caption out of the caption of the repost, some spin text and tokens. Just make a list of accounts you want to repost from (these need to post the kind of content you want to repost consistently as the repost will be chosen randomly from the last x posts). Also choose accounts who use engaging content and captions.
advantage:
- set up once and forget (no need to manually look for pics all couple of weeks)
- if the repost account creates good individual 'call to action' captions, you copy them so the work is already done for you
