How to group selected blade Id's to Multiselect option?

[x186855]

I have a desired list of blades and I had filtered out only those blade id's and now while creating a multiselect list I only want those blades to be grouped without using asterisk in value. Below is my query, so for "ALL" option I want only the blades filtered out in my search query. Currently, I'm using asterisk as a value but it is giving all the blades, please help me out so I can group only the desired blades against field name "ALL".

    <label>SIP Blades</label>
    <choice value="*">All</choice>
    <prefix>(</prefix>
    <suffix>)</suffix>
    <valuePrefix>Source="</valuePrefix>
    <valueSuffix>"</valueSuffix>
    <delimiter> OR </delimiter>
    <fieldForLabel>Source</fieldForLabel>
    <fieldForValue>Source</fieldForValue>
