I don't think you can access the 'styles' you create in assy mode for drawing views, unfortunately.
What you can do is set a component to be phantom.
- On the layout tab, select 'Component Display from the 'Edit' section.
- Look, the Menu Manager! Select 'Style' in the top section and at the bottom whatever best reflects where you want it shown as phantom - Picked View, This Sheet or All Sheets.
- Select the item(s) you want as phantom
- Middle mouse for done when you've picked all the components you want and a new section of the menu manager will appear.
- There you can select whether you want it standard, phantom opaque, phantom transparent or a user color.
You can also repeat those steps but select HLR display to control the display of hidden lines per component or individually blank or unblank components. The HLR display doesn't change the entire component to hidden, only allows you to control hidden line removal on a per component basis.
