How to send extra POST parameters with Stripe component?

[karh]

How can I achieve the following?

1. I have a stripe client side component set up:
   

   

2. In the Dynamic Attributes → Line Items I am sending an array of data (shopping cart)

3. In the server action I can use the data from that Line Items parameter, but I would like to send extra data to this server action so I can execute more complex logic. How do I do that?

I found one way to do it, but would love official support so it’s easier to add multiple get variables.

Workaround until that time:

1. Add a url parameter manually to the session-url :
   
2. In my example, the variable can be used in the server action as $_GET.wj_schedule_id
