Address question bip version mauling


I have few questions and I would really appreciate your assistance:

  1. Do you know or did you encounter a crypto app that supports ZCASH using bip49 instead of bip44 ?

  2. Do you know a bypass that will create a transaction in the native app of ZCASH (zcashd) that spends UTXOs which belongs to addresses that generated using BIP49 (t3… address - not multisig) ?

Are you familiar with a manipulation to simulate this address as if it was generated as multisig from our private key ?

  1. Do you know if there are any plans to implement BIP49 in ZCASH coin ?

Thank you,
