make category.xml > attribs overrideable in menu item

Hi there,

[Problem]
I want to display the same category with with different category-parameters, using two menu items.
I know that menuitems can override view parameters. But I am missing the ability to override fields that I made in category.xml, e.g.

<fields name="attribs">
        <fieldset name="attribs" addfieldpath="/administrator/components/com_flexicontent/elements">
            <field name="myField" type="list" default="common" label="myField" description="myField"> [...]

[Details]
They do appear in
category > display > layout > layout parameters > layout configuration for "my tmpl name"

Can you make them accessible also in
menu item (with active "Override view parameters") > Parameters > layout?

Thanks a lot for looking into this,
kath
