Store Lambda expressions as variable

Is it possible to store a lambda expression as a variable and use it in multiple places. My db objects have an Id as int and a UId as an uniqueidentifier and I have to write very similar expressions when selecting based on Id or UId.

Lambda:

var result = await this.Worker.GetRepo<Category>().DbSet
    .Include(cat => cat.InfoItems)
    .Include(cat => cat.Products)
        .ThenInclude(prd => prd.InfoItems)
    .Include(cat => cat.Products)
        .ThenInclude(prd => prd.GraphicItems)
            .ThenInclude(itm => itm.Graphic)
                .ThenInclude(gfx => gfx.Items)
    .Include(cat => cat.GraphicItems)
        .ThenInclude(gfx => gfx.Graphic)
            .ThenInclude(gfx => gfx.Items)
    .Include(m => m.Modules)
    .SingleAsync(cat => cat.Id.Equals(id));

Is it possible to:

var expression = .Include(cat => cat.InfoItems)
    .Include(cat => cat.Products)
        .ThenInclude(prd => prd.InfoItems)
    .Include(cat => cat.Products)
        .ThenInclude(prd => prd.GraphicItems)
            .ThenInclude(itm => itm.Graphic)
                .ThenInclude(gfx => gfx.Items)
    .Include(cat => cat.GraphicItems)
        .ThenInclude(gfx => gfx.Graphic)
            .ThenInclude(gfx => gfx.Items)
    .Include(m => m.Modules);

then use the variable like:

await this.Worker.GetRepo<Category>().expression.SingleAsync(cat => cat.Id.Equals(id));

await this.Worker.GetRepo<Category>().expression.SingleAsync(cat => cat.UId.Equals(uid));

I know the syntax is wrong, it's just what I'm looking for.
