How to slow Motion Scroll Effects and anchors?

I am using a down pointing arrow to cue the user to scroll down to the next section. I thought I could automate by linking the arrow to an anchor that is positioned down the page. Cool, it works. However, the jump is so fast that all the fancy Motion Scroll Effects I'm using on the next section are nearly invisible. I see that this site does what I want when you press the "Scroll Down" graphic: Digital Marketing Agency in Johannesburg, South Africa

Is it possible to slow down the browser scroll when jumping to an anchor, using only Muse?

Thanks,
