It's too tricky for a UNION because the total I need at the bottom can only be achieved with a higher level grouping

DDL

create table LeadTracker

(property_name varchar(30), lead_id int);

insert into LeadTracker values

('Property1', 18709),

('Property1', 18323),

('Property1', 19547),

('Property2', 18709),

('Property2', 19015),

('Property2', 18323),

('Property2', 19547),

('Property3', 19015),

('Property3', 18323),

('Property3', 19547),

('Property4', 19015),

('Property4', 19547);

--first query shows how many leads were sent to each property and totals it at the bottom: 12 leads total.

select

property_name,

count(distinct lead_id)

from leadtracker

group by property_name;

--second query shows that only 4 were unique leads. I need for this 'unique lead' total to appear beneath the total leads.

select

count(distinct lead_id)

from LeadTracker;

I need the results to look like this, all in single column

select

property_name,

count(distinct lead_id) as leads_sent

from leadtracker

group by property_name

union all

Select property_name = 'Total', leads_sent = 12;

PLUS

Select count(distinct lead_id) 'TOTAL UNIQUE leads only'

from LeadTracker;

please look at image file I attached. How can I do this in SSRS?
