Question - Accessing tribute information

[Naturesong]

Hi, looking for details on tribute cost.

The Character TLO has the following members which give useful information on tribute:

ActiveFavorCost​

CareerFavor​

CurrentFavor​

TributeActive​

TributeTimer​

I'm looking for a way to identify the cost if I activate the personal tribute set I have saved.
${Me.ActiveFavorCost} is the closest, but I have to turn on tribute to get the value.

Alternatively, I can get the value I'm after from the tribute window directly: /echo ${Window[TributeBenefitWnd/TBWP_CostLabel].Text}, but this value is only exposed when the tribute window is opened on the character.

Does anyone know if this value is exposed elsewhere?
