EL expression based on the work area or tab

Hello

I have added order entry screen in two work area 1) Seeded 'Order Managment' 2) Custom 'Sales Quote'. I have given role to the user because of which both this work area is available to the user. I want to enforce some controls on order entry screen under the 'Sales Quote' area using sand box personalization. How can I use the work area name 'Sales Quote' in the EL expression to change the properties of the fields on the order entry screen under 'Sales Quote' work area. This should not affect the Order Entry screen under the Seeded
