How to control 2 buttons with an IOLinc?

Hi All

I am trying to use a remote control to control my roller shades. The remote control has two simple buttons; up and down. The buttons are activated when the contacts (for each button) are connected. I was thinking of using the IOLinc, for the buttons. But with the available options, I believe I would need to wire the COM to one side of the contact and the N/O to the other. That way when I activate the IOLinc, the COM and N/O would close, and thus connect the contact.

But this would require one IOLinc per button. Kind of a pricey way to control the shades. I was wondering if there's a slick way to use one IOLinc to control the up and down motion of the buttons. Or what other option I have to control the buttons.

Thanks
