HTML report geenration in postman

I want to generate single html report for multiple collection or for multiple folders in a collection in Postman

I tried running two folders of same collection simultanesously, but it is generating separate html reports for both.

Command I ran:-

newman run SOLR_filterPartNumber.postman_collection.json --folder PartNumberNoLongdescription -d testData_noLongDescription.csv --reporters=cli,htmlextra,csv 

newman run SOLR_filterPartNumber.postman_collection.json --folder FilterByPartNUmber -d testData_PartNumber.csv --reporters=cli,htmlextra,csv
