Is there a way I can invest say £100 just into free funds within pies once a month and then have the auto invest come out of those free funds. That way my bank account only shows one deposit so easier to keep track of rather than say £20 coming out of my bank account every week. Whenever I look to invest money it just asks me how I want it distributed. Or will it take it out if general free funds within the ISA??? Thanks so much.
