Restrict choices in Select box variable in Catalog Item

[Nithin21]

In table cmdb_ci_appl, i have "FieldB" which is string field with the below choices

Choice 1 on table cmdb_ci_appl

Choice 2 on table cmdb_ci_server

Choice 3 on table cmdb_ci_db_instance

I have a variable on Catalog item with variable "FieldA"

Type = Select Box

Choice table = cmdb_ci_appl

Choice field = FieldB

How to get only Choice 1 (i.e. Choice defined for table cmdb_ci_appl) In "FieldA" of the catalog variable 

Ryte now it displays 

Choice1

Choice2

Choice3

You can use a client script with g_form.removeOption() to remove options from a choice list.

I was hoping to avoid Client scripts as it introduces a lot of scripting.

Is it not possible to achieve using choice field / reference qualifier
