Additional 'Filter' & 'Header Lock' Features

On the 'Supplier Onboarding' section, could we please add a filter to sort by 'Invited by' so we can group people together by the request(s) they send? In addition, if we could lock the header for 'company name', 'status', 'invite email'.. etc, that would be awesome! 

Please see Christine Afenir, Customer Success Manager, Enterprise, for details. We just discussed on our catch-up call 1pm EST today. 

Thank you!
