Add Whole Share and End Date in "Investment Plan"

[fagallo]

Is your feature request related to a problem? Please describe.

My broker does not support fractional shares, so e.g. if I do an Investment Plans of 500 EUR of a stock which is 110 per share, I buy 4 with an expense of 440. PP instead records automatically 4.54 shares, and each month I have to change all the automated transactions with the exact number of shares (4).
Furthermore, it would be important to add the end date as well as the start date to be able to stop the plan.

Describe the solution you'd like

Ideally, you should put a check mark for "Whole shares only". And add an end date field.

Describe alternatives you've considered

Otherwise, wouldn't it be possible to create an "investment plan" based on the number of shares of stock instead of one based on the total amount?
