You may have the option to aggregate properties together and treat that group as a single entity. Basically, you could make Group A for three rental properties. Each property would be listed separately in the assets section for that group. The only downside is that you can't realize all of your losses until you sell or dispose of all the properties in that group. This and more is covered in IRC Section 469(c)(7)(A)
I've ran across of few in these forums over the years who do this because they have more than the 45 properties the program can handle individually.
