It is useful in purchasing departments to create a workflow for purchase agreements with an approval depending on amount or quantity. However, that is limited due to the lack of options.

So a conditional decision to reflect the following would help:

when purchase agreement amount is small or equal to value 5000.00 GBP then approve by A, otherwise approve by B.

when purchase agreement quantity is larger than value 1000 then approve by A, otherwise approve by B.
