Hello Dennis,Currently, the support is limited to adding a text field using the previously mentioned filter. However, we plan to update and modify this filter in our next release. After this update, you’ll be able to use the enhanced filter to meet your specific requirements.
You can keep track of the progress of the issue from here https://github.com/multivendorx/MultiVendorX/issues/723.

In the meantime, it would be really great if you can give us 5/5 review here: https://wordpress.org/support/plugin/dc-woocommerce-multi-vendor/reviews/#new-post
This would motivate the team further to do their job more efficiently.
