How to fill Due amount automatically in Checkout Link?

[asrp]

I have created a unique Checkout link with an option "Allow buyer to set price" because payable amount is not fixed. We email this link to the customer for payment.

Problem: This link works ok, but occasionally customers put wrong amount in the checkout link.

Question: Is it possible to populate the due amount field automatically? Means customer doesn't need to fill up amount manually.

Is it possible, to add the due amount to the payment link URL somehow? which can be used to populate the form filed. (similar concept to the courier Tracking number).

Could you please advise a solution or workaround to solve this issue?

P.S. I don't want to create an individual invoice for each customer, which is troublesome.

Creating an individual checkout link for each amount would be the only workaround here, @asrp. I'm sorry there isn't a workaround that would bypass the step of creating individual invoices, or links, at the moment!
