Purchasing Enhanced License Photos in the most inexpensive way (Perhaps a set/bundle)

To whom it may concern,

Hi there, I currently have a subscription with Adobe Creative cloud and all, I have a few credits left available on my account.. I know I cannot use it to redeem extended ones and I can only acquire standard licenses, but I would like to purchase a few enhanced license images (about 28 of them in total) and I'm wondering if I could get those enhanced licenses as a set in the most inexpensive way using my existing subscription plan? Is there any way I can get credit packs to redeem extended license images? Our company has been invested with Adobe Creative tools and assets for a while, and you guys have helpful for our businesses. We've been grateful! And I would appreciate so much any help on that. I'm looking forward to hearing answers, and the detailed information and solution you can give us. Thank you so much.

Sincerely,

J
