Reading other directory attributes, how ?

[goga63]

Hi !
Is it possible in the formula attribute Dynamic Component to apply the attribute value from the other directory attributes ? For example :
in the directory 'price_attributes' is the attribute 'cost' value '25'
Can this value (25) to use in formulas attributes from the directory 'dynamic_attributes' ?
Transfer attribute 'cost' from the directory 'price_attributes' in the directory 'dynamic_attributes' is not desirable.
