can I change the forest plot generated by the dmetar package for a subgroup meta analysis?

I have used the function

subgroup.analysis.mixed.effects(x = meta1,
                                subgroups = salt1$sample.type)

from the dmetar package [][1]to do a subgroup analysis but the forest plot is practically unreadable due to the range of the effect sizes. Is there a way to limit the x axis to a specific range in the dmetar package?
