Request: Split bolus as bolus + ecarbs

Hey!

As far as I am aware, this feature is not implemented and I couldnt find a similar request. I think it would be of great help (at least for how I use AAPS).

My "workflow" when eating is to enter a bolus and then enter E-Carbs seperately, which the SMB will deal with. I think that is how most people use it.

The thing is, for almost all foods you would need to enter E-Carbs when using SMB (unless you eat candy all day and just need a fast bolus). At least for me, it doesnt work without. You need to enter bolus and E-Carbs seperately, in a different menu. Its inconvenient and therefor I often forget to enter E-Carbs.

It would be nice to be able to input a direct bolus and E-Carbs at the same time, much like a split bolus.
If would be very straightforward and only needs 4 inputs:

• amount of carbs/KH/BE
• % of carbs/KH/BE to be given directly
• Timespan of E-Carbs
• Delay of bolus/E-Carbs

Here are a few examples:

• You eat Pizza and bolus 40g carbs after 15 minutes. 40 E-Carbs will be input over 4 hours. Your input: 80g carbs, 50% direct, 4h timespan, 15min delay
• You eat sugar and bolus 24 carbs after 0 minutes, 0 E-Carbs will be input over 0 hours. Input: 24g carbs, 100% direct
• You eat a chicken filet and bolus 0 carbs after 0 minutes. 12 E-Carbs will be input over 4 hours. Input: 12g carbs, 0% direct, 4h delay.

On top of that, the input could easily be done with 4 sliders and the distribution could be shown as a very simple graph.

What do you think of the idea? Maybe this function could be activated in settings, just like the SuperBolus, and shown as a seperate button at the bottom. Or the feature could be added to the already existing bolus calculator? I could not be of much help with the implementation, I think. I could refine the concept and write some java/kotlin.

Thanks a lot :) Nils

Start by examining the existing bolus calculator and SuperBolus settings or button, which the issue proposes as integration points. Clarify the four inputs, their timing and carbohydrate distribution behavior, then define tests covering direct bolus, extended E-Carbs, delays, and zero-duration cases.
