RTS did allow copy of a cell and then highlight and paste of an entire column, or whatever was selected. I'm not sure why I didn't try that right off. I was highlighting and trying to right click edit after a copy.
While the program seems a little slow to load, compared to other RTS software, there are zero problems reading/writing here with RTS. Also, with the Adjust Setting Speed on "Fast", it takes about a minute. When set to "Normal" it is about twice as long. (Windows 10, 8GB RAM, i5 CPU, 64 bit laptop)
The software provides a column for entering in NAC for P25 and whatever else depending on the digital mode, as well as the option for digital squelch. While those using RTS may now know this, others may not. Additionally, I am unsure if it had the column previously, but it is definitely working now. I'm new here

Anyways, I keyed up a couple of P25 repeaters and no problem hearing myself, whether or not I programmed the NAC...as long as the Operating Mode was correct.
I have yet to copy and paste from another RTS software for a VR-500, so we'll see how that goes. Actually, I'll pull freqs from a D74A as there are more things in common.
Here is where I am at:
