T1 Instalment Schedule

T1
1

Would it be possible to allow the instalment worksheet to incorporate instalments that have already been made, i.e., clients may have already made March 15th personal tax instalment, which I would like to enter into the worksheet and then have the worksheet update the instalments to indicate the instalment that has been paid and recalculate future instalments based on the March 15th instalment made. This can be done manually on the letter but it is very time consuming especially since most of my T1 returns are done after March 15th. If this is not available in the T2 program it would be great for that also. Thank you.
