There are countless other songs with temporary key changes.
Can iRealPro incorporate this?
It does not currently. I understand what you mean as this can happen in a section (like bridge, chorus) where it is in another key and indicated as you are suggesting. There are no plans to add this. I presume you are using the player, because if it was just a chart you were wanting, you could add text to indicate the key as you normally would on paper but create the chords as if based in the one key so the numbers translate correctly.
