Sharepoitn List, Columns, Datasource

Hi

Is it possible for a Sharepoint list column to lookup values from an excel sheet stored in O365?  I can see it is easy to do this in a PowerApps form to a new field, but not in a list lookup column?  (Cannot add datasource in the lookup column to the excel file)

If I do this in the PowerApps form, then it seems that this field cannot be shown in the list view, so cannot filter on it in list view?

thanks
