Having two callsigns

[VK5TOM]

Anyone know what the go is applying for a 2 letter callsign and keeping a 3 letter callsign?

I haven't completed the process to be absolutely certain but when I was considering it I understood I could apply for as many callsigns as I was willing to pay for,  and that being now advanced that included 2-letter callsigns.

I didn't go through with it as my preferred 2-letter callsign is still in use
