Colour Data field in AF Attribute

We are creating hundreds of different attributes in AF, mostly based on templates and using these in PIVision. One thing that is annoying is when you make the PIVision image you have to manually change the colour of the symbol you use/trend you created etc to reflect the medium of the attribute that is used. Sometimes you even have to change the HEX colour code since it does not match the standard colour palette. What I am suggesting is to have a Colour Datafield in System Explorer for attributes. Here we can define the colour (via HEX code or another way), so when this attribute is used in PIVision, the colour is automatically selected. No Colour Set = Manual/Default PIVision Colour. Colour Set = Colour chosen by default in PIVision. Should be overridable in PIVision if people wish etc.
