All access plan

I’ve purchased maybe 10? extensions so far, and I’m about to buy another one. Do you offer any simple way to switch to the all access pass instead? I’m worried if I buy it now, I’ll be charged for it each year PLUS charged for each extension separately. Is there a way to consolidate and buy an all access plan at cost minus the cost of all the extensions I’ve already purchased? I’m bad at numbers and just trying to figure out the easiest, most cost-effective way of doing this.

and before you ask, I didn’t buy all access to begin with because I had no plans to buy extensions. Each time I came into extra money, I’d buy one to make my site a little better. Now I’ve almost bought them all separately!

thank you!
