Customfield String with Cart Variant Price

Hello Adrian,

long time ago since i post the last request.
Is it maybe now possible to add a String Custom Field with price Variant?
I have such fields in added to Virtuemart Custom field but in VMVendor the price field is not showing.

In Virtuemart Backend my settings are like this:
Custom Field - String
Cart Attribute - yes
Cart Input - yes

In backend of Virtuemart i can add this custom field an it has two option values. First is for the text second is for the price.
In VM Vendor add product form i only have the First field for the text but no price field.

Is it possible for you to add this option?
Maybe i can send some money for this...

Hope to hear from you
Greetings
