ExcelCellStyle in mendix 4

I am trying to set the color of an excel cel in Mendix 4. I'm trying to use a single style for multiple cells but i cannot find any implementation of IExcelCellStyle. The Mendix 5 documentation however does mention an implementation. Does Mendix 4 have an implementation and if so, where can i find it?

The implementation of the IExcelCellStyle interface is only used internally, that should be the case for both Mendix 4 and 5. I'm not really into this code so I can't help you much, but have you tried getting a style from 1 cell and just setting it to others? The actual color-setting methods are in the interface so that might work.
