Permalinks, Registration and "Sold by"

Good day

I have searched high and low for answers to the following issues I’m having, but I haven’t found the right answers. I hope that you might be able to help me.

I’ve installed WCFM – WooCommerce Multivendor Marketplace, WCFM – WooCommerce Frontend Manager (free) and WCFM – WooCommerce Multivendor Membership. Before installing your products I tried out Dokan as well as WCMp.

1. Vendor store name in url

I’m building a multivendor store where vendors will most probably have products with the same name. For this reason, I would like to have the vendor store name in the permalink so that identical products won’t have a number added to their url. Products are added to four categories, so at the moment the structure is /category/product. I would like it to be /category/vendor/product, or /vendor/category/product would be fine too.

Is there any value that could be added to the permalink structure, such as adding %vendor_store% or anything like that?
I have enabled ‘Product Multi-vendor’ under Marketplace Settings.

The theme I’m using is Woodstock by Themash Design.

2. Vendor registration
Is the a way to set the default vendor role as ‘Shop Vendor’ and not just ‘Vendor’? Or would I have to do this manually?

3. ‘Sold by’ position on product listings
I have set ‘Sold By Position’ to the required position on product pages but is there a way to change where it appears on listings (on pages that show all products in a category)? Right now it’s under the product photo and I would like to move it down to under the short description.

4. Issues caused by previous multivendor plugins
Would you recommend running the migration tool in order to get rid of redundant database entries or settings that might interfere with the way WCfM operates? Would this override and reset everything I’ve done so far? Right now everything seems to be running well with registration etc.

Please respond at your earliest convenience
