Allow multiselect values, to behave the same as category_ids, to allow relative changes.

So my thoughts on the matter, if you have multiple "multiselect" attributes that need this.

required columns:
sku, store, ... multiselect_reset, multiselectColumn1, ... multiselectColumnX,

column: multiselect_reset
values "attribute1::0;attribute2::0;...;attributeX::0" // otherwise it's default behaviour.

column: "attribute1"
values: "select1, +select2, -select3"
etc.

select1 would be set;
added select 2;
remove select 3;

column: "attribute2"
values: "+select2"
result: select2, would just be added to the magento product.

column: "attribute3"
values: "-select3"
result: select3, would just be removed (if it existed) from the magento product.
