Building multiple Report without build new using the old

In our organisation I have created lots of dashboards and given relevant users access to dashboards. While developing the dashboard as a developer is their any way
how would I create multiple reports without having to rebuild my entire data set for each report? Currently I have one data set which is linked to a single PBX file. I make import all my data via this, create measures, make visuals etc and then publish to PowerBI in a report (and dataset) called "origanation Data".

Is there a way I can create multiple reports without having to build a wholoe new data set each time which would be a mess to maintain.

Thanks.
