Auto select `Shares` from linked security account when manually adding dividends

[RoChess]

Adding "Dividends..." after selecting a security, it defaults to Shares on all accounts combined.

When holding the same security on multiple accounts it would be nice when adding dividend entry on a selected account that it automatically selects the linked share-entry for the deposit/securities account that the dividend is being added to manually.

Steps to take each time currently is to use chevron drop-down menu on "Shares" to select the matching one to ensure the math works on dividend payment per shares as I often normally enter just the credit-note total during manual entry.
