[Enhancement]--Bolus scheduling for large meal

I'd like to submit an enhancement request for bolus scheduling. This would be beneficial for large meal corrections for those that suffer insulin leaks from their pump.

For example, I am unable to give boluses of >4u from my Dash pump without insulin leakage. This isn't the fault of AAPS, but it does mess with my blood sugars, nonetheless. But, I tend to forget to re-bolus for larger meals (say 10u are necessary, but I end up bolusing only 6u). And yes, this causes my BG to spike, which means even more insulin is needed to treat the meal and now the high.

Being able to split up a bolus into, say, 4u every 20 minutes is a more precise way to get exactly the dose you input, rather than relying on SMB.

No files, tests, or entry points are named. Start by locating the existing bolus and SMB scheduling flows, then clarify how split amounts and intervals should be configured, scheduled, cancelled, and confirmed; done would mean delivering the requested total dose in scheduled portions without relying on memory.
