Rebar Custom Properties/Nesting

What's going on guys? New user to zz here- met the guys at WOC and was impressed with the takeoff software.

I'm a small business owner-operator. We typically take on commercial work ranging from $100-450k with the occasional outlier for a larger paving job.

I am utilizing zzTakeoff for efficiency to win back time with my family instead of staring at a computer and a legal pad for hours on end.

With that background out of the way, I have familiarized myself with the concrete takeoff side of the software as it seems built in via volume/sf formulas. I have watched the advanced concrete/rebar video and I see the items for rebar added to calculate rebar and add this to the takeoff as well. I don't mind inputting the information, but where can I find the rebar weight information as well as the custom property information to nest the rebar formulas into my software to be able to integrate the weight takeoff on rebar into my reports?

I am new to takeoff software, so my apologies if this sound very novice or if this is considered trade secret. I am willing to pay for a takeoff pro to guide me through adding these properties on my software for time saving/accuracy alone.

Thanks in advance!
