Block Attribute value vs Parameter from DesignTable

Dear All,

Is there any way to update automatically an attribute value of a block when modifying the value of a parameter (dropdown list made from a design table)

If the attribute value cannot be linked to the value of the parameter, can I insert a Mtext with a field in my block to get the selceted value of the parameter.

Would it be possible to concatenate 2 parameters values in this Mtext or attribute ?

TY
