Split payment with 1/n with auto rounding of split payments

I am using auto rounding to $1 using Calculation Type and also enabled Auto Rounding in Settings > Program Settings > Payment Screen Settings (to also round orders on payment screen). This works fine, except when using 1/n split. In a situation where the total is $51, split by 2 using 1/n button, the total comes to $25.50:

How can I get it so the split amount is also rounded to $1 but not affecting the total (i.e. total must remain at $51) - so ideally it would split as $25 and $26 ?

I saw an old V4 question relating to something similar as this, although the user was using Payment Processors for rounding, @emre mentioned about a rounding method of 1/n split like I mentioned and that it would be available in next release, which at that time would have been the initial release of V5, but it doesn’t appear to be working like that.

Here is my auto rounding Calculation Type:
