If you require to compare different systems against each other, much simpler to just run the backtests separately and compare the results, even export the results to excel and do whatever you need to do there.
It should be possible to do this all within AB, but the effort required to write the portfolio backtest AFL would probably take longer than to separately write, test and begin trading them

Well said! Be warned not to fell into the trap of spending all your
time in learning to program instead of learing to trade. I have used
a trial version of the Builder version of TradingBlox (IMHO, the
turtle and pro versions with only cann't systems don't worth the
money). It was a real eye-opener! I would have bought it if myself
not a programmer and can handle Ami pretty well. I learned a lot of
system building concepts from the trial version and used them in my
Ami AFL. The multi system simulation with detailed reports and rigid
risk control is still hard to do with Ami, if possible at all. If
you are in trading long enough, risk control and position sizing is
more important than all those fancy indicators.
