[c-nsp] LACPDUs interval in IOS-XR

certain Cisco Catalyst platforms(for example 6500), Nexus(for example
Nexus 5000) and ASR's support fast LACPDUs interval, i.e. they ask
LACP neighbor to send LACPDUs in fast rate. In case of IOS-XR used by
ASR's it is possible to configure LACPDUs interval from 0.1s to
1s(must be multiple of 100ms):

RP/0/RSP0/CPU0:ASR(config-if)#lacp period ?
  <100-1000>  Specify the requested transmission period (in
milliseconds) for the partner system (must be multiple of 100; default
  short       Configure usage of the LACP short interval
RP/0/RSP0/CPU0:ASR(config-if)#lacp period

However, is there a way to configure for example 5 second interval? As
much as I searched, it does not seem to be possible and next option is
to fall back to 30 second "normal" interval.
