Set Frame Marker Color with Blueprint

We have made this little internal tool using a combination of blueprint and python that will generate marked frames based on a date range set by the user. This works perfectly fine, but I would also like to set the color on the marked frames using this tool. I know I can do it manually, but haven’t found anything yet that allows me to do it using blueprint. Anyone got any tips for this?

Hi,
did you find a solution for that?
Currently also trying to change the Color and Comment of the marked frame. However, I can not access the property.
