Custom fields and short desscription

Hello mate,

1) Does it export short description? can it be set to export it as description and ignore wc description? how?
2) Can we export custom fields? any?
3) Custom meta field price per item can be exported as cost per item in shopify or a cutom meta created? how to select the custom metafield on both?
4) VEndors (like dokan vendors or clients vendors) can be exported as vendors of shopify? how to?
5) Fre version skipped on products with variants because it has “all as variant how can we avoid that?
Regards
