Setting up IRA Plans in Benefits.

Hello,

In PS 9.2, where do we enter flat amount contributions for IRA plan types?

For e.g: if it is Roth IRA then contribution limit on annual basis is $7000 , for age 50 and above, it is $8000

where do I do this setup?

I tried in Savings plan, but it only allows percentage.

Is there a MOS note regarding IRA plans?

Also, these benefit plans are not showing up in Program setup when I go there to assign these plans. I have not assigned default deduction codes to IRA benefit plans yet. Could that be the reason for the why these plans are not available to select from on the programs page?
