Dividend reinvestment option needs to allow fractional quantities

Hi, can you please allow fractional shares/units as an option for reinvestment of distributions (rather than just the existing rounding up or down options). Vanguard managed funds allow for full reinvestment ie if dividend dollar amount paid equals 10.63 units at the current price, then vanguard lets me purchase exactly 10.63 units as reinvestment rather than disregarding the 0.63 units and only reinvesting the 10 units. At the moment I can manually edit the distributions to add the fractional units and that then corrects the reinvestment purchase quantities, but it's a bit of a unnecessary pain and takes a lot more time as have to correct every entry- especially when loading up all my prior years info like I'm doing now as a newbie to Navexa. Plus if you just ignore all the fractional units then the totals can be wrong and will say you've gone into negative quantities when selling everything. I'm getting an error message currently for one holding like this as I haven't fully updated each of the dividends and so it says I have negative holdings. Not sure if this issue lies at the importing data stage or just in how navexa processes it. Thanks :)
