I noticed that the premium page (aka pricing table) is not customizable.
I think that it is not very useful as is. In fact it has too much friction for marketing.
I think that whatever service need to have one or more landing pages to sell it. Also this landing pages must be frictionless. I would suggest two solution:
1) Having the ability to link the purchase button from the landing pages whatever way i want to create them or
2) Having a shortcode to place in the landing page to expand the pricing table.
