Making Revisions to IMDb Pro Listing

I have the IMDb Pro Basic plan which doesn't allow me to do much on IMDb Pro. I don't really need or use IMDb Pro, and I can't justify the expense. However, I have listings that I've created, for projects that I'm attached to, that need to be revised. I can't edit them. I need the next level of IMDb Pro to be able to make simple changes to these listings. Since I created the listings, and they're my projects, I should be able to edit and revise them without having to pay for IMDb Pro. I think this is a flaw in the system. Contributors should be able to edit and revise listings they've created. Sure, if they're trying to edit someone else's creations, they should be paying membership fees. So, is there a way I can edit the listings I created, without having to put out money I don't currently have? Thank you for your time.
