xCoba: applying two metrics, ToBasis and ToValues in a notebook?

[Purnendu Karmakar]

Dear friends, 

I am interested in applying two different metrics on the same expression in xCoba, in one notebook. In order to define two metrics, I must write:

MetricInBasis[g, -B1, deSitter]

MetricCompute[g, B1, All, CVSimplify -> Simplify]

and similarly for metric 2. We can always define ToBasis[B1] and ToBasis[B2] distinguishable. However, could we define two "ToValues" for two different metrics? Or else, do you suggest any alternative solution to apply two metrics? 

Thanks and regards, Purnendu
