I want to add a block in left column of only my module, not whole website.
If I place it in <default> tag it will be shown in whole website, but I want to do something like <mymodule_default>, is it possible ?
I know I can place my block in every layout_handler like
<mymodule_controllername_actionname>
<reference name="left">
<block type="mymodule/block" name="left_navigation" before="-" template="mymodule/left-nav.phtml" />
</reference>
</mymodule_controllername_actionname>
but this is not what I want, I want to do it as
<mymodule_default>
<reference name="left">
<block type="mymodule/block" name="left_navigation" before="-" template="mymodule/left-nav.phtml" />
</reference>
</mymodule_default>
Or it is not preferable ?? Thanks
