[h323plus] Issue with H.263 codecs set

Hi all, 
I need an advice - how to work with set of H.263 codecs. Basically, I have all H.263 codec types capability implemented: H.263, H.263-1998 and H.263-2000. All these capabilities uses same H245_VideoCapability::e_h263VideoCapability value for GetSubType function. In result my localCapabilities variable has all these 3 capabilities as well. 
When I receiving remote capabilities the remoteCapabilities variable is loading by H323Capabilities::H323Capabilities(const H323Connection & connection, const H245_TerminalCapabilitySet & pdu) constructor and the function uses code like this (simplified): 
H323Capability * capability = localCapabilities.FindCapability(pdu.m_capabilityTable[i].m_capability, capabilityNo, pdu); if (capability != NULL)  {           H323Capability * copy = (H323Capability *)capability->Clone();           copy->SetCapabilityNumber(capabilityNo);           if (copy->OnReceivedPDU(pdu.m_capabilityTable[i].m_capability))             table.Append(copy);           else             delete copy; } 
The main issue -  localCapabilities.FindCapability function returns any first H.263 Capability from it's table, no matter which particular H.263 remote Capability was used, it only checks MainType and SubType... In result if remote side send me, for example, H.263-1998, but I have H.263 and H.263-1998 - I will have H.263 in result...  
Now I'm trying to override Connection::OnReceivedCapabilitySet(const H245_TerminalCapabilitySet & pdu) function, extract H.263 codecs manually, store all these capabilities and update remoteCapabilities after, but may be exists a proper solution for this case? 

Thanks -- Iurii Gordiienko
