You are able to do this. In your first post and every other post, at the end of it, provide a link to all of your sessions. Problem is of course, you earn more if you charge people $9.99 instead of getting a $0.01 upvote...
The convention for links to posts is easy:
steemit.com/{First Tag}/{@username}/{post-title-without-spaces}
You could even link to posts you haven't put in yet, as long as you determine the title and tags. Doing it this way just feels scammy. Not saying it is a scam, I'm sure people feel they get their money's worth, but to leave steem and go somewhere else so you charge a dollar rate per episode seems shitty.
Or maybe you just don't like that after 7 days any new people that come up won't be able to give you upvotes...
I don´t understand everything that you write, but sounds great... i´m new here and i hope learn more of you :)
