'Transfering' Finale's spacing into Sibelius

[OCTO]

I am very new with Sibelius. I have tried to figure out how Sibelius calculate spacing but I am very unsure. Sibelius' default is very ...strange to me.
Anyone here that can enlighten me how to cleverly edit Sibelius' spacing, for instance transfering Finale's Golden Section spacing into Sibelius, or any other variants of JW Spacing.

Many thanks in advance.
(I am slowly leaving Finale).

Get Bob Zwalich's note spacing plug-in. It has most, if not all of JW Spacing options plus other options (for example, the ability to expand note spacing by a certain percentage).

Also, its the only way to have several spacing algorithms in the same document.

Thank you. I will explore that now.
