[solved] Making huge batches of unique T5577 that emulate ProxCardII

I bought several rfid door locks for my company and they're all FSK compatible only. I had boxes of EM4100 cards and they're not compatible with my locks since they're PSK. not a big deal I bought them before I knew we were doing secure door locks. so I bought a bunch of T5577 cards and a proxmark3 I was disappointed that they came setup for PSK encoding I was however able to clone a compatible card and the T5577 works with my door. I have a card writer where I enter the Facility ID and a starting number, check a box that says +1 and start programming my cards one by one. it's quick, simple and it puts them in ascending order. Is there a similar method of programming my cards as ProxCard II or any other FSK modulated card. I'd hate to do hundreds of cards one at a time calculating the checksum and building from the ground up. I'm assuming that someone has built a tool to do this.

Thank you for your help.

EM100x and blank T5577 chips use ASK modulation.

The lf_bulk_program.lua is great. I am wondering though - is there any other script or modification - to be able to produce a large number of tags at once programmed to HID 26 bit, but rather than using the standard H10301 format, to be able to specify a specific parity bit for each tag (eg. even or odd)?
