Custom Labeling support on workflow

Describe the solution you'd like

We are planning to move Image scanning to Github Actions by help of Prisma Cloud given workflow,.
In twistcli there is a parameter where we can define a custom image label as an user input.
--custom-labels (Include the image custom labels in the results.)

But there is no method to define --custom-label parameter on Github Actions workflow. Can you add a additional input to workflow where we can define a custom label as a parameter.
