Can Rise be purchased separately?

I would like to chime in here and say it would be great to buy a separate seat just for RISE. Articulate team should consider allowing this if at least one seat user at the company purchased the full package. For example, I am an ID and utilize the full package so I have this functionality. Other members of the team have expressed an interest in Rise exclusively as they don't use the other tools. To have user seats attached to our account that only allow that functionality would be a super helpful add-on for companies that don't want to buy full package additional seats but would be open to a smaller figure for just that one software piece.
