Re-Use of existing element-rules by reference possible?

Hi,

I configured many number conversion rules in form of SIP-MANIPULATION entries, as we need to map numbers from the official phone network to numbers in a customer (country-wide) internal network, which does not work by a simple rule, but requires dozens of element rules. As we need to convert SIP header fields

• request-uri
• To
• From
• Contact
• P-Asserted-Identity

I had to re-enter existing element rules for two (R-URI + To) or three (From + PAI + Contact) times. This usually looks like this small exemplary excerpt:

sip-manipulation

   name                          MapE164ToInternalnumber

   header-rule

      name                          HR_MapE164ToInternalnumber_RU

      header-name                   request-uri

      action                        manipulate

      comparison-type               pattern-rule

      element-rule
