Is there a way to use findgroups() so that it is based on order in the matrix instead of alphabetical?

I am using findgroups() as an integral part of the script I'm currently working with, but the way that findgroups() outputs its groups is causing issues.
x = {'m1' 'n1' 'k1' 'k1' 'p1' 'p1' 'b1' 'b1' 'b1'}
[g,g_id] = findgroups(x)
What I would prefer is if g outputted as [1 2 3 3 4 4 5 5 5] and g_id as {'m1' 'n1' 'k1' 'p1' 'b1'}. Is there any way to do this?

There doesn’t appear to be that option for findgroups. If you only have one vector, the unique function can do thaat using the 'stable' setOrder —
x = {'m1' 'n1' 'k1' 'k1' 'p1' 'p1' 'b1' 'b1' 'b1'}
[g,~,g_id] = unique(x,'stable')
.
