How to limit share price calculation to thousandths? (Q Mac)

Tesa

Quicken has always calculated the share price based on the Total Cost and the Number of Shares but they don't limit the decimal places which can go to 8 decimal places (i.e. @71.94051134). All my investments round to the third decimal place (thousandths). Is there a way to set this limit in Quicken so that I don't have rounding differences from my investment statements? I enter my investments manually.
