As sallen07 has already noted, there is no way to program a single tower that is part of a simulcast site. All of the related transmit points use the same set of frequencies, each frequency in use is carrying the exact same radio traffic as all of the others. The variations in distance between your location, and the individual transmitter sites means that signals, carrying the exact same data & voice arrive at your location at separate times, due to the varying distances between your location & the sites. While that variance is infinitesimal, the signals are out of sync enough to prevent the scanner from properly decoding the voice signals.
The link in post 29, above, gives a more complete description of simulcast description, with a few suggestions that might help in some cases, though not all.
What, sort of, works for me, using my 325P2 on the two Dallas sites of this system, is to lay my 325P2 flat on a desktop. Try that, using the OEM antenna, not a gain antenna such as the Remtronix antennas made for 700 & 800Mhz systems. Using a 'worse' antenna, pointed horizontally rather then vertically, reduces the signal strength reaching the scanner, in some cases, washing out the more out of phase signals. Also try moving the scanner around. Sometimes a move of only a few feet (even only one, sometimes) makes a significant difference in how the scanner might deal with simulcast issues.

The scanner only accepts 4 digits (right of the decimal place). That last, fifth digit, is not significant in how the scanner can perform.
The 325P2 is not a good choice for simulcast systems. The best is the new SDS150, followed closely by the SDS100 & SDS200. The 436HP & 536HP are not as good with simulcast as the SDS scanners, getting 70 to 80% of the SDS100 on a field test I did on local simulcast systems. The 325P2 is below the SDS & x36HP scanners' performance, getting 50 to 60% of some local systems' transmissions. My Whistler TRX-1 is well below 50% in effectiveness.
