User Relationships: send implied relationship *after* the implying one is approved

Hi,
I'm using your User Relationship module (version 2.8) in Drupal 5 and
I have a little problem (don't know if it's a bug or not). I make an
example to better explain what I mean.

I have two relationships (both one-way with approval), "supplier"
implies "customer" and vice versa "customer" implies "supplier" (both
Strict and Reverse are checked).
User A wants to be supplier of B and so requests "supplier" approval to B.

At this moment nothing is approved, but (here comes the problem) A
immediately receives "customer" request from B, so (if A approves this "customer"
request) can start and also immediately end these two relationships
even if B hasn't approved.

Could you tell me how can I make B approve the "supplier"
request and only after this send "customer" request to A?

Thank you very much in advance (it's a little bit urgent) :)

Bye!
