create dynamic worksheet list

Hi,

I am using =REPLACE(GET.WORKBOOK(1),1,FIND("]",GET.WORKBOOK(1)),"") with Name Manager and =ListSheets,A1 to list my worksheets in my excel file, when new sheets are created they are added to the list using a sequential numbering in column A.
The file has now been saved to SharePoint and when opening the files using Excel Online the updates to the lists don't happen when new sheets are created - I understand this is due to limited functions in Excel Online.

Is there a alternative to the Name Manager solution that can create a dynamic list of worksheets that works with Excel Online ?

(the file is replicated many time on the ShPt site and i don't want to open each in the desktop app - updates need to be dynamic as they are linked into PowerBi)
