Expected Behavior

Hi, I just have question for how to generate a QR code.
I have requirement that the generated QR code should be Version 2 and ECC Q.
I know the limited data length is 29, but my data length is 30.
However, my data looks like this: 1X1234567890123456789012345:XX
in this case, I think i can split it to 3 different parts using different encode mode.
like: 1X -- Alpha Numeric
1234567890123456789012345 -- Numeric
:XX -- AlphaNumeric
this should work in this case.

But I'm not sure is it possible to do this?

QR code spec definitely allows for mixed-mode encoding, but there is no easy implementation available within QRCoder to do this currently.
