Referencing ranges in other sheets within NextCloud Office

Hello,

There’s a cool formula in Google Sheets called IMPORTRANGE that allows you to reference ranges in other sheets.
Does NextCloud Office have a similar feature? According to this article, this feature exists in Collabora Office, but I can’t find it in the interface of NextCloud Office.

Does not seem to be currently supported by collabora online, see Import data from other spreadsheets (IMPORTRANGE / workbook links) · Issue #5562 · CollaboraOnline/online · GitHub

OnlyOffice has some support for such links, see:

Hello! Is the problem solved?
