I don't understand what you mean.
You can achieve that with a custom CSS class.
Something like this (add in extra.less temlate):
CSS:
.itemForumLeft
{
position: absolute;
top: 200px;
left: 100px;
}
.itemForumRight
{
position: absolute;
top: 200px;
right: 100px;
}
Create a package for the left side and add in the "Css class" input the
itemForumLeft
class and
itemForumRight
for the other package. You can select position "Below top breadcrumb" for both.
