Add value to create new (compounded?) value

Unsure if compounded is the right term but anyway....I am trying to calculate a new attribute based on existing values - usually easy to do - but in this case the expression must reference each subsequent attribute value in an original attribute. Best explained by the graphic below:

'StaticValue' is the original value and 'CompoundedValue' is the attribute I want to create. The first value will be unchanged but each subsequent value in the 'CompoundedValue' attribute must reflect the corresponding 'StaticValue' value.

Can I do a 'circular' reference like this in FME?
