It is possible spinnerfield in Ext.Picker

It is possible to insert a spinnerfield inside a Picker? Or it is best to insert it in an ActionSheet?

I'm developing a mobile commerce app. Products are in a dataview (vertical list) and on itemtap I display an ActionSheet /Picker showing all variations and the possibility for the user to select a quantity for each variation (so user can buy, for example, two items of the red variation and one of the green variation).

I would use multille spinnerfield for the quantity selector, arranged vertically.

Best the action sheet or the picker? I need scrolling as variations may be up to 10
