Reinvesting dividends

Quick question please, probably a daft one.
When you have stocks in a pie with reinvesting dividends does the reinvestment share itself across the pie or to the share it came from?

It shares across the pie according to the target percentages.

Just as I thought thank you. Wish we could have a way to reinvest in each separate instrument if wanted to. Other than put each one in its own pie.

You could alternatively turn off auto invest and then select what you wish the dividend to be attributed too within the pie

Thanks, yes have done that. My pies are not set up as pies, more like folders. Not balanced, just away to group sections of stock together for ease of monitoring. EG all my financials in one, tech in another etc.
