When dealing with Cloud Feeds for credit cards, you can have unimportant and common vendors, like gas stations and convenience stores. There are ways to not overload the vendor list.
If the payee is not important, you can create a generic vendor for this purpose, say Misc. Charges, and tie all the imported expenses like gas, convenience store charges, etc. to this vendor. It is a good practice to mention the vendor in the description when adding this credit card charge to BQE CORE.
Note: Only vendors of type Consultant and Contract Employee show up in most drop-down lists. So you might want to tag this generic vendor as one of the above two types so that it appears in the Cloud Feeds and other drop-downs.
