Is your feature request related to a problem? Please describe.

We can specify whatever icon we want as a spark background in progess bar aura.
However, we can't change said icon based on dynamic information in conditions section as there is no simple option in GUI.

Here is a short demo:

Note
The static icon on the left is a separate aura and is not part of the progress bar aura.

What is available at the moment

What I want to achieve is having each spark icon to be equivalent to the bar color.

Here are current possibilities in the condition's GUI:

Option	Image	About
Icon		related to the progress bar icon, not spark icon
Spark		limited options without icon

Describe the solution you'd like

I would like spark option to have an additional Icon option in conditions section.

Ticks, which are the more modern replacement for sparks now have conditions for changing the displayed icon.
