Airtable to Reddit Automation

I have a list of subreddits with their assigned tags. I would like to have another table of images and videos in which I’ll put tags next to the images and it automatically populates subreddits that are relevant to that content. based on that I want a row to be added to another table which will be responsible for scheduling reddit posts with a specific time interval. I am currently using postpone and zapier , if you have suggestions I’m open to that
