Multiple Accounts under Unique Wallet (unique mnemonic)

[t2ruva]

Dear Sir/Mam
In the old version of Keplr I can create multiple accounts under a unique mnemonics which helps me to classify/manage my funds and interactions.
But with the current version it seems Keplr does not support "add account" any more. It is only available "add wallet" which creates independent account of my main one with different mnemonics
Moreover if I create a multiple account with another wallet, I can't import this to Keplr since Keplr sees only the first account and ignoring others. Which eventually results unable to manage my funds
Kindly ask to analyze this situation and bring this feature back
Best Regards
