Answer: It is not clear about which document you are talking about, but some documents in the ISO 27001 & ISO 22301 Premium Documentation Toolkit are common for both ISMS and BCMS (e.g., Document control procedure and Internal audit Procedure), or can be used to support both systems, so it is possible to use them for both systems.
Included in your toolkit there is a List of Documents file which shows which clauses of both standards are covered by each document. Another way to identify this common use is by the commentaries included in each template. Some comments specifically identifies which text can be adjusted so the document can cover both standards.
