Merge two hard drives into 1

As I'm now working from home, I have had to load my Mac with a lot of new data and information, as it turns out I am running out of space. I have my OS drive and have an additional drive called Data where I keep all the non OS - work related files. I have a 1TB drive that I have formatted to APFS, and it is working fine, but I need to be able to see all the data as one drive.

How do I merge both drives, Data and New Data into one "virtual" drive ?? Does OSX have that option ? In Linux I can make LVms or logical volumes, how can I do this on my mac ?

Thanks

Manuel
